When heavy rainfall takes place the discharge and load of the river carries is increased. This load it carries is then deposited inside the cove where the currents are not strong and the water isn’t deep enough to carry away the sediments. Now with the low currents present in the cove and longshore drift the sediments carried by the river accumulates around its mouth contributing to the beach along the coastline which accounts for the miscellaneous sediments and igneous rocks found on the beach shown in the figure below. Sediment Characteristics of beach at Don Christopher’s Cove. Nature Of Wave The nature of the wave is of most importance. At the area of research the waves were observed to be constructive, however the nature of the waves in the area of Robin’s Bay is destructive under the influence of the North East Trade Winds giving the waves more energy causing the nature of the waves to be destructive. Inside the cove the waves were observed as constructive. This was concluded from the spilling profile of the waves observed when the waves are breaking on the shore. The swash of the waves were greater than the backwash and the beach profile was not steep. Fig 1.1 shows
